Spiral Gears are extreme difficult to be formed, and it’s also very hard to eject out. The tools are also very hard to manufacture, by using our multiple axis EDM machine, we can guarantee the accuracy of the spiral teeth, and can forge the gear within 35 spiral angle. The external spline is varied to obtain the desired fit. The very simplest method of initially selecting of involute spline based on a shaft dia is to arrive at an initial Pitch circle dia (D) and a module (m). eg. a spline for a 50mm OD spline with say a module of 2mm would have a PCD (D) of 50 - 2 = 48mm.
